Variable resistor |
摘要 |
A variable resistor having a short-circuiting member which is displaced in response to the generation of abnormally high heat in the resistance member of the variable resistor with a piece thereof in contact to short-circuit the input and output terminals of the resistance member. This results in a bypass for large current, so that a protection circuit in an output amplifier is operated to suspend the generation of heat.
