Electrical Connectors
What is a Connector?
A connector is an electromechanical device used to join two electrical parts together, generally this would be connecting a cable to a system or cable to another cable within an electrical circuit. There are many different types of connectors that can accomplish this. They can be used to connect power, data and fibre and can come in different shapes, sizes and materials. They can also be waterproof, dustproof and heat proof to various industry ratings. Our sales team is ready to help you with any queries.
What Do We Supply?
We offer a broad range of electrical connectors, including:
Appliance couplers
Hazardous area connectors
'Buccaneer' sealed connectors
General purpose connectors and accessories
Why Choose E. Preston?
As a distributor, we stock and supply electrical connectors from excellent manufacturers like Bulgin, Hylec, Schurter and TE. The quality and reliability of their products is second to none and we are delighted to be a distributor for them. We distribute throughout the UK from our premises in Dukinfield, Cheshire, and aim send as many orders out for next day delivery as possible.
As a company we are driven by what might be seen as ‘old fashioned’ values of making sure we return phone calls when asked, and treating customers with respect. Ultimately, great customer service is important to us and one of the reasons why we have thrived as a company.

Our excellent customer service is also reflected in our provision of expert technical assistance and advice that our highly experienced staff can provide over the phone, which our customers use and find invaluable.
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.
