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

Thanks.
