Abstract
A concise electronic timer is composed of an adjustable resistor, a supercapacitor and an electromagnetic relay. After a main power is turned off, electricity supplied from the capacitor to the relay will extend or actuate the operation of a load until the discharge of the capacitor is over. Incorporating the resistor with the other two elements, the discharge time of the capacitor can be altered linearly by the resistor, therefore, a linear arrangement of delay extension and time of activation is attained. The simple, compact and economical timer can be used for indoor and outdoor illumination, monitoring security systems, as well as actuating systems.
