控制应用经常要求将一只继电器锁存定位,直到需要改变其状态时为止。完成这个任务的是锁存继电器。当给它们发送一个脉冲时,它们可能保持在当前状态,也可能改变状态,具体取决于脉冲的极性以及继电器当前状态。图1中电路会根据一
Control applications often require that a relay be latched and positioned until it needs to change its state. The task of completing this task is to latch the relay. Depending on the polarity of the pulse and the current state of the relay, they may remain in their current state or send a pulse when they are sent. Figure 1 circuit will be based on a
