Abstract
Disclosed herein is a leakage protector, which includes a housing. A base plate and a brush are arranged in the housing. A first conducting strip and a second conducting strip spaced apart are arranged on the base plate. The brush is provided with contact pins to contact the first conducting strip and the second conducting strip, respectively. The second conducting strip can generate different analog voltages, and the first conducting strip is configured to transmit different analog voltages to a microprocessor. A user can drive the brush to move through an actuating part, and set the power-on time of the leakage protector in one step.
