the products of micro switch manufacturers occasionally have some failures in use. after long-term research, we have summarized a set of solutions for solving micro switch failures. let's take a look at it, just for your reference:
question 1: when the valve body is closed: micro switch 1, 3 feet are closed, 1, 2 feet are disconnected; assuming that the left switch 1 or 3 feet are disconnected, the right switch is normal, the phenomenon is: the left switch is turned on, the pulse does not respond , turn on the right switch, pulse left and right burners to ignite alternately;
reason analysis: when the left switch is turned on, the pulse is out of power, so there is no response. when the right switch is turned on, pins 1 and 3 of the left switch are in disconnection, which is the same as the state when the switch is turned on. the pulse will consider the left switch to be on. in the starting state, the left and right burners alternately ignite.
question 2: when the valve body is opened: the micro switch 1, 2 feet are closed, and the 1, 3 feet are disconnected;
turn on the left switch, the pulse has no response, turn on the right switch, pulse the right furnace head to ignite, and then turn on the left switch, the left furnace ignites normally;
reason analysis: when the left switch is turned on, the pulse is out of power, so there is no response. when the right switch is turned on, the pulse is normally powered, and pins 1 and 3 of the left switch are closed. the state is the same as when the switch is closed, and then turn on the left switch. , so the left burner ignites normally.
