Solenoids
What are Solenoids?
A solenoid is a type of electromagnet formed by a helical coil of wire. When an electric current passes through this coil, it generates a controlled magnetic field. Here are some key points about solenoids:
Structure: A solenoid typically consists of a long piece of wire wound into a coil. The length of the coil is substantially greater than its diameter
Magnetic Field: The electric current flowing through the coil produces a uniform magnetic field inside the solenoid. This field can be used to create linear motion or to control other magnetic fields
Applications: Solenoids are widely used in various devices, including car starters, doorbells, and washing machines. They convert electrical energy into mechanical energy, making them essential in many electromechanical systems
What Do We Supply?
We supply a great range of solenoids, including:
AC Laminated Solenoid
DC C-Frame Solenoid
DC D-Frame Solenoid
Linear Solenoid
Rotary Solenoid
Why Choose E. Preston?
Since our inception in 1980, our business focus has been on providing two things: a reputation for outstanding customer service, and an unbeatable range and stock of electrical and electronic components.
We feel we have achieved that at E Preston, and that probably explains our company growth over the years. We do not want to become complacent though, and we always work hard to exceed customer’s expectations when they deal with us, if we can.
Our service is unashamedly a little old fashioned, ensuring we follow up on promises to customers, and phoning back when we said we were going to. We also do our best to ensure the customer receives their order next day. You can also talk to us about flexible payment terms, if needed.

DSTH DIP Switch: Robust Standard Profile and 2.54mm Pitch THT (through-hole technology) Switch
2.54mm standard pitch
Robust THT design
Extended actuator for easy switching
Available in 3 colours: black, red, blue
The DSTH DIP Switch is a robust, standard-profile and 2.54 mm pitch THT (through-hole technology) switch. It enables electronic devices to be configured directly at hardware level. Addresses, communication parameters, logic states and operating modes can be set easily and clearly, without modifying software or firmware.
Electrically, the DSTH uses SPST contacts and offers 2~10, 12 multiply positions. Ratings are 25 mA at 24 V for frequently changing switching states and 100 mA at 50 V for constant switching states. Initial contact resistance is ≤ 50 mΩ and ≤ 100 mΩ after the specified tests. Further specifications include a dielectric strength of 500 V AC for one minute, 2,000 mechanical switching cycles and an operating force of ≤ 8 N. The operating temperature range extends from -40 °C to +85 °C.
Typical applications include PLC controls, industrial servers, medical devices, robotics, air-conditioning systems and household appliances. In these applications, the DSTH can be used for RS485 and Modbus addressing, BIOS/CMOS settings, as well as the configuration of hardware parameters, functions and operating modes. Combining proven performance, competitive cost and fast availability, DSTH is an ideal solution for OEMs seeking a reliable alternative to premium-priced standard DIP switch brands.
Eaton’s AFDD provides comprehensive protection against electrical fires triggered by arc faults. This all-in-one device combines the functions of a residual-current circuit breaker, miniature circuit breaker, and arc fault detection, protecting against electric shock, overcurrent, short circuits, and arc faults. Through continuous electronic cable monitoring, the device detects arc faults and trips automatically to reduce the risk of residential electrical fires. It provides electricians with a more efficient, standards-compliant solution for enhanced safety.
Tripping indicators show status and trip cause, saving fault‑finding time
AFDD busbar as accessory supports easy and flexible installation
Single Module AFDD Eaton’s single-module AFDD range delivers all-in-one protection in a compact design. Engineered for residential and commercial applications, it enables space-saving distribution boards and seamless upgrades of existing installations, while supporting compliance with BS 7671 AFDD requirements.
Features:
Arc fault, overload, short circuit & residual current protection
Only 18 mm width
6 & 10kA
6 - 40A
B & C Characteristic
Type A
Idn 30mA
Types
Type -A: Protects against AC and pulsating DC residual currents.
Type -Li/A: As Type -A, but in addition it is short-time delayed. Highly reliable against unwanted tripping.
Type -G/A: 10 ms time delay in order to avoid unwanted nuisance tripping (e.g. during thunderstorms).
Type -F: Higher immunity against smooth DC currents and enhanced surge current proof capabilities.
