Can be used with any number of normally open switches. Suitable for mercury switches that allow them to approach when moving or when the bicycle is lifted off, standing side by side, or being pushed away from the center station. Use a microswitch to protect the removable panel and the back, etc., while at least one of the switches remains closed and the alarm sounds a cover. After about two minutes, the switch is turned back on and the alarm will reset. How long it takes to turn it off depends on the characteristics of the components actually used. However, with the year-on-year growth point, you can adjust the time to meet your requirements by changing the value of C1. Boards and switches must be guaranteed from the elements. Moist or condensed can cause malfunction. Without a terminal block, the board is small. Ideally, you should try to find enough remaining space to fit its flute. A power cord fuse for 1 amp is close. This protects the wiring. Instead of using a push button switch, you can use a hidden switch, or you can use a normally closed contact for a small relay. The line, which is the ignition coil when energized. Then each time the ignition is turned on, the alarm will set itself, it is not sing high-key, and the circuit uses almost no current. This should make it useful in other situations. For example, powered by dry batteries, relays and alarms to accommodate voltages, it may be internally loaded with a computer or any other hazard that is picked up and carried away. Low standby current and automatic reset, that is to say, this external on/off switch may not be necessary for the application's supporting materials, the alarm board, parts list, a complete build including a detailed guide circuit description and more .
