Cherry Electrical Products UK has announced that its general purpose GP and E ranges of precision, long life snap action switches cost up to 20 per cent less than other devices commonly available, yet retain all the performance of their more expensive competitors’ products. GP heavy duty switches can handle up to 15A and have a mechanical life of one million actuations; E Series devices are available in single and double-pole configurations with five current ratings from 0.1 to 30.1A.

Featuring an ultra small travel differential and a wide variety of actuators, GP series snap switches are also optionally available with low operating force. Screw or solder terminations can be specified. Internally, the switches have a high quality of build, featuring insert moulded terminal pins, gold over silver plated contacts and a high-strength titanium copper alloy spring. The housing comprises a rugged phenolic case and cover. E series devices feature a similarly high build quality and are optionally available with operating temperatures up to 200degC.

Applications include pressure switches, commercial hand dryers, garage door sensors, fork lift truck motor stops, lift control, x-ray equipment and a wide range of other industrial machinery.
  
Comments Mark Mills (Switches & Controls Sales Manager) at Cherry Electrical Products UK: “GP and E series general purpose devices will give Cherry the opportunity to grow our share of both the commercial and industrial markets, where a more heavy duty micro switch is required.  We will not only save customers money but also, as an established player in the switch market, we wil bring our service culture to these new opportunities.”

Metal Switches with High Resistance to Destructive
Elements, Fully Illuminated Actuating Surface

The new MSM CS metal switch from SCHURTER is equipped with an actuator made of highly durable ceramic. Ceramic is a new technology employed in the production of an electro-mechanical switch.  The new switch provides novel features that open up entirely new areas of application. The actuator material of the MSM CS is resistant to scratches, abrasion, impact and chemicals.

The non-illuminated version has a translucent white actuating surface. Lettering is black and is applied directly onto the ceramic material. Due to the base material and the lettering process, the lettering is resistant to scratches and to common cleaning agents. In the case of switches designed with illumination, the actuator surface fully illuminates uniformly across the entire surface. Lettering and symbols can also be applied. The standard black lettering provides a positive effect against the illuminated actuator, while negative lettering provides an inverse effect.

The MSM CS is extremely robust and meets vandal-proof demands due to the low profile of the front structure (1.7 mm), the IP 69K protection class and the high level of impact resistance. The switch is available in 19 mm and 22 mm mounting diameters. Different contact configurations are offered over a range of 30 VDC to 250 VAC for the admissible switching voltage; switching currents are permissible from 0.1 to 10 Amperes. The MSM CS is equipped with quick connect terminals to allow for fast connections. The wires are connected to the switching element which is subsequently snapped onto the switch housing.

Schurter announces the USF 0402 surface mount fuse, making it the smallest new member to its USF family.  This tiny new addition performs with a Super Quick Acting (FF) characteristic at rated currents ranging from 0.375 - 4A at 32 VDC, 5A at 24 VDC.

 
The USF 0402 is ideally suited for secondary circuits where space is critical, such as those found in consumer electronics. Compared to like products on the market, it provides increased reliability because of its ability to dissipate less heat. Typical applications are battery operated handheld and portable electronic devices, like laptops, cell phones, GPS systems, PDA’s and many other devices that have demand for increasingly smaller components. 

The Schurter USF range of chip fuses includes the 0402, 0603 and 1206. The size of the 0402 measures a fractional 1.05 mm x .55mm x 0.475 and is 2-3 times smaller than the 0603. A letter marking on each fuse indicates its current rating to ensure tracking of the proper fuse through the production process.  The fuse is UL 248-14 approved and carries cURus approval. It also holds a Free of CCC certificate from China. Terminals are gold-plated copper alloy. The USF 0402 comes packaged in tapes of 1K, 5K or 15K pieces on reels.

Honeywell introduces its SS361RT and SS461R Bipolar Latch, Hall-Effect Magnetic Position Sensors, giving customers the opportunity to help reduce manufacturing costs.

The SS361RT and SS461R sensors’ enhanced sensitivity enables the use of less expensive magnets in some applications. The SS361RT sensor’s very small footprint takes up less space on the printed circuit board, typically allowing for a reduction in costs. Additionally, the SS361RT sensor is supplied on tape and reel, allowing for automated, highvolume, lower-cost pick-and-place assembly.

Honeywell designed the SS361RT and SS461R sensors for potential use in industrial applications (e.g., speed and RPM sensing, tachometer, flow-rate sensing, valve/damper position, brushless dc motors, variable speed drives, motor and fan control, and robotics control), medical applications (motor assemblies, medication dispense control), and transportation motion control applications (e.g., RPM sensing, tachometer, motor and fan control, electric window lifts, convertible roof positioning, and transmission positioning).

Honeywell’s SS361RT and SS461R sensors feature a 3 V supply voltage capability for low-voltage applications. The sensors are available in two package styles, providing application flexibility. The SS361RT’s miniature SOT-23 surface mount package utilizes a tape and reel format; the SS461R’s flat TO-92 style is available in bulk (1,000 units per bag).

Three new families of pushbutton and rocker switches now immediately available: to suit automotive, medical, and power equipment

  
Cherry Electrical Products’ new KC, KF and KD round waterproof switches comply with IP56 or IP65 specifications to provide a cost-effective solution for the vast number of applications requiring protection from water and dust ingress, such as garden sprayers, powered garden tools, lawnmowers, on and off-road vehicles and medical equipment.  Three product families are available: the KD and KC series of round rocker switches and the KF switch series for products requiring a pushbutton solution.

IP56-rated KC series switches are designed to fit panel cut-outs of 0.795in (20.20mm) diameter, and are available in lighted and non-lighted versions, with black actuator and housing for the non-lighted version and red actuator, black housing and red lens for the lighted version.  This series of single-pole, single-throw (SPST) function switches offers multiple terminal options.  Electrical ratings include 16A 125VAC, 10A 250VAC, 20A 14VDC, 10A 28VDC and an EN61058 rated version in 10(4)A 250V.

KD series switches are available in two versions: DPST (double pole, single throw) and DPDT (double pole, double throw).  Featuring snap-in mounting to fit the same aperture sizes as the KC series, they can be ordered in lighted and non-lighted versions and handle DC and AC loadings to the following specifications: 16A 125VAC, 10A 250VAC, 20A 14VDC, 10A 28VDC and have quick connect 0.187in (4.76mm) terminals.

For applications requiring a round pushbutton switch rather than a rocker, the KF-series is offered in five different versions, both SPST and DPST and both types of switch can be supplied lit and unlit as required. Maintained-action and momentary switching is a further option. The KF series has quick-connect 0.187in (4.76mm) terminals and is IP-65 compliant. Electrical ratings are: 20A 14VDC and 10A 28VDC, and in UL 1054 ratings of 10A 125VAC; 6A 250VAC; 1/2HP; 125/250VAC are available. 

All three switch families are robust in use, offering a mechanical life of 100,000 cycles and a long electrical life of between 6,000 and 25,000 cycles.
