Therefore, in the switch operating direction between each switch,
By arranging a shared power line shared by these switches,
It is possible to use an auto output mechanism that simplifies the connection circuit, but in this case, multiple switches are used at the same time.
When turned on, a plurality of total currents become values close to other output signal values via the shared power supply line, resulting in malfunction.

For example, even if you perform automatic output to open and close the window,
Although not locked, multiple switches are turned on, so a value close to the lock current that locks the window is detected,
Occasionally the opening / closing operation of windows was stopped on the way.
