本文介绍的这种开关适用于各种无触点的开关电路.通过一些辅助电路可制成有触点的开关,以便与强电电路衔接.触摸开关电路如图1所示.由二个D型触发器组成,分别接成单稳态和双稳态电路.揿一次开关SW(用硅导电橡胶制成),晶体管BG1的基极端的负脉冲经反相器反相后加入触发器IC1(单稳态)的S_1端,使Q_1端为高电平.该上升沿再触发IC2(双稳态)触发器的CP_2端,使
This article describes the switch for a variety of non-contact switch circuit can be made through a number of auxiliary circuit contact switch, in order to connect with the strong circuit. Touch switch circuit shown in Figure 1. By two D Type flip-flop, respectively connected to the monostable and bistable circuit. 揿 a switch SW (made of silicon conductive rubber), the negative terminal of the transistor BG1 negative pulse inverted inverter after the addition of flip-flop IC1 ( Monostable) S_1 end, so that Q_1 end is high. The rising edge trigger IC2 (bistable) trigger CP_2 end, so that
