Paul Charman - Stock Controller
"Very nice people who go out of their way help you with your requests for service and delivery."

Manuel Blanco - Senior Electrical Design Engineer
"High Voltage Relays, that can switch reliably in our electrostatic-charge plate monitor, are essential to ensure accurate and precise measurements. The Pickering 100HV SIP instrumentation grade reed relay characteristics were suitable for our application enabling us to repeatably increase our measurements with a high degree of quality. I would highly recommend Pickering to anyone considering mission-critical high voltage switching in their applications."

Arun Kumar - Executive Director Electronics
"Recently we had an application to disconnect a battery High voltage sense line in the simplest possible way in the smallest footprint. The obvious solution is your high voltage relays. 50 installations and 100s of hours later, they are performing immaculately!"

Marc Santiago - Manufacturing Technician
"In my 16 years in repairing semiconductor boards, Pickering relays have consistently had the most sturdy and reliable components in performance."

Stuart MacDonald - Production Manager
"Pickering is an excellent company to deal with, professional, providing quality & reliable relays. You can see current stock on the website available to purchase & the price. Or you can talk to their Sales Dept who can advise you on the lead-time & price FRO of any current non-stock items. Available stock is dispatched as soon as they receive your PO: & non-stock items typically are delivered 1 to 2 weeks earlier than the promised lead time with an email to let you know they have been dispatched."

Basil Pawlykiwskyj - Test Engineer
"Have been using Pickering relays for over 20 years plus for different applications. Their standard of quality over time has never let me down especially the 110 high density relays which have been reliable in the ATE systems and in some bespoke instrumentation testers that I have designed in the past with other companies that I have worked for. Just cannot fault them."

Ian Joyce - Power Electronics Engineer
"High-fidelity sound equipment is my hobby. I was building a design published in "Hi-Fi News" that recommended low capacitance high-quality reed relays but I was unable to find a source in the USA at that time. Pickering kindly supplied 2 off 106-1-c-5/3 samples that met my needs and they are still working perfectly."

David Hyde - Electronics Engineer
"I have used Pickering reed relays in a couple of high voltage antenna switching applications with great success. By setting the max delay in my transmitter (after keying) and pairing a NC with a NO reed relay I was able to build a very simple circuit to allow me to have a different receive antenna from the transmit antenna. The switches performed perfectly with virtually no signal loss."
Matteo Dacunto - Electronics Engineer
"Very good firm and reed relays at affordable prices."

Reliability through Quality 
55 years of outstanding reputation for extended relay lifetime derived from continuous staged manufacturing inspection, strenuous full range thermal cycling and 100% testing for all operating parameters.

Reliability through Design
Our environmentally compliant Reed Relays use Softcenter™ technology, therefore minimizing internal stresses on the reed switch, resulting in an extended life & contact resistance stability.

Switching Performance
Our formerless coil technology enables the use of higher AT grade switches; delivering more robust and reliable switching over lifetime, higher standoff voltages, tighter operating windows and a greater immunity to stray magnetic fields.

Cost & Size Peformance Leading edge mu-metal magnetically screened reed relays allow ultra-high packing densities, saving significant PCB space resulting in lower costs, whilst eliminating magnetic interaction effects.


Switching up to 12.5kV. Choice of 1 Form A (SPST NO), 2 Form A (DPST NO) & 1 Form B (SPST NC).

Five times smaller than industry standard relays without compromising on switching performance.

50 Ohms and 75 Ohms reed relays for up to 3GHz for RF and high-speed digital switching. 

Upcoming events for 2024

Our reed relays use only the highest performance components combined with exceptional quality control.

Part of the privately-owned Pickering Group, company operations employ around 250 staff across quality accredited factories in the UK and the Czech Republic, supplying demanding Aerospace, Infrastructure, Test & Measurement and ATE applications worldwide.
