Abstract

An apparatus may include a first terminal, a second terminal, a direct current (DC) motor (202a, 302a, 402a, 502a, 602a), a brake mechanism (204a, 304a, 404a, 504a, 604a), and a voltage blocking mechanism. The DC motor (202a, 302a, 402a, 502a, 602a) may be configured to operate when a voltage is applied across the first terminal and the second terminal. The brake mechanism (204a, 304a, 404a, 504a, 604a) may be configured to apply braking to the DC motor (202a, 302a, 402a, 502a, 602a) when no voltage is present across the first terminal and the second terminal, and remove the braking from the DC motor (202a, 302a, 402a, 502a, 602a) when the voltage is applied across the first terminal and the second terminal. The voltage blocking mechanism may be configured to prevent the DC motor (202a, 302a, 402a, 502a, 602a) from operating when the voltage is applied across the first terminal and the second terminal until the braking from the brake mechanism is removed from the DC motor (202a, 302a, 402a, 502a, 602a).
