The 131 series are single throw, normally open, miniature mercury reed relays. Reeds are hermetically sealed in glass tubes with trace amounts of liquid mercury to provide continuously refreshed contact surfaces for extremely long life.

The 134 series offers double throw contacts. Both are capable.

For Additional Configuration please use the RFQ/RFI tab above to submit your request.
