Title:
ELECTROSTATIC RELAY
Document Type and Number:
Japanese Patent JPS60241324
Kind Code:
A
Abstract:
A static relay for low DC voltages includes output transistor (Ts) with its emitter connected to an output terminal supplying a load (Z) further connected to a common supply terminal. The base of the output transistion (Ts) is supplied via the main current path of a current injection transistor (Ti) acted upon via a control electrode. The current injection transistor (Ti) is supplied with an auxiliary voltage (Vaux) which is higher than the voltage (Vbat) feeding the output transistor (Ts). A detection transistor (Tc) has its emitter-base path, which includes a base resistor (Rb), connected parallel to the base-emitter path of the output transistor (Ts) and delivers at its collector a detection signal representative of the state of the load (Z).
