Abstract

PURPOSE: To enable a single circuit constitution to perform real-time and delay time switch driving operations by providing 1stW3rd switching states where a discharge line is activated at the 1st stage, a reference voltage is applied across a comparing method at the 2nd stage and the discharge line is cut off at the 3rd stage.
CONSTITUTION: Switch circuit 4 with three switching states is activated with discharge line 5 grounded via S2 when traveling contact (c) of switch S2 is changed over to fixed contact (b) in the 1st state. In the 2nd state, traveling contact (c) of S1 connected to fixed contact (a) of switch S2 is switched to fixed contact (b) so as to ground one terminal of a series connection circuit of resistances R5 and R6 for activation, thereby applying divided voltage Vc to the base of transistor Q2. In the 3rd state, discharge line 5 is unactivated and the generation of reference voltage Vc is also prevented. Consequently, both real-time and delay-time switch driving operations can be done by a single circuit constitution.
