Contact rating 5 amp at e. The integrated circuit will be unresponsive to input pulses of less than eight volts, thereby guaranteeing noise immunity while securing definite triggering at the operating voltage of the car battery and the circuit breaker. Values up to pF. As most electronic casings are nothing more than metal or plastic boxes which do not lend themselves to a good finish, a commercially made case was required, this was found cleverly disguised as a table mirror stand in a local shop.
