An electrical parking brake device includes an operation switch and a control circuit. The operation switch includes a switch button, miniature switches, operation switch terminals and inside conductors, the switch button being in one of an On state, an Off state and a neutral state, the miniature switches operating in conjunction with the state of the switch button. The control circuit includes control circuit terminals, a switch verification circuit, management circuitry and brake application command circuitry, the management circuitry managing the electrical parking brake device. The operation switch defines closed circuits that are independent in terms of a pair of the operation switch terminals, for each of the operating states. The closed circuits are closed circuits that, when one or more of the miniature switches fail, avoids influence of the failure, by the miniature switches other than the one or more failing miniature switches.
