Power on/off circuit with lock function

摘要: A power on/off circuit with lock function having a momentary type main switch (10), two-circuit two-contact (11), switching state holding (17), load (23, 25) and supply (24). One of the circuits in (11) is connected between (10) input terminal (CK) (17). The other reset (CLR) held by circuit, kept unless signal given to circuit. has only generate signal, so that does not cut off current as conventional shaver.
