I have a component I am trying to identify. It consists of a glass tube about 3/4" long and 1/8" diameter. Inside this tube are 2 blades that look like the might contact each other where they overlap slightly. There is a wire coming in from either end into the glass tube and the ends are fused shut(melted) The only markings on the outside are as follows: RS 338 147 Can anyone identify what this is?
Thanks, BV
Hook up an ohmmeter and wave a magnet near it.

They are widely used in magnet/reed switch intrusion detectors.
Also in 45 rpm jukebox applications as the end-of-record trip switch.
I need 1 or 2 of these and am having trouble finding a source. Does anyone know of a source for small quantity? In the US. Thanks. BV

I've bought a number of them on ebay, they're cheap.
