Product Details
Form A & C Reed Switches
These dry-reed switches have been hermetically sealed in a gas-filled glass envelope. Actuation is done with an electro-magnet, a permanent magnet or a combination of both. If you prefer, they can be placed alongside a coil and actuated when a current is applied to the coil. They feature single pole, single throw, normally open contacts and have two magnetically actuated reeds.
There is a wide selection to choose from. You can select different lengths and each length has various sensitivity options.
