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
Sound like a reed switch. Uses a magnet or magnetic field to operate it.
Reed switch.

Thank you all....Its definitely a reed switch
I am having trouble finding a source for this switch. Can anyone direct me to a source for 1 0 2 of these components?

method=sea...
Found the bare-glass type:
I am surprised this stuff can handle 500mA and 1A continuously when making. We have plenty of these in the matrix boards (128 of then in one card) used in the telephone exchange that I worked. They are smaller and carry less current. The problem was that they get sticky after few tens of thousand times of switching on and off. Had to change them frequently.
