Push switch

摘要

The invention provides a push switch including a keytop movable in a first direction, a switch, first and second circuit boards, an electronic component mounted on the second circuit board, first and second circuits electrically connected to the switch, and a body. The switch is turned on or off in response to movement of the keytop. The first circuit on the first circuit board is configured to protect the switch. The second circuit on the second circuit board is configured to actuate the electronic component in response to a turn-on or turn-off of the switch. The body includes a main body and first and second holders. The first holder at the main body holds the first circuit board. The second holder at the main body or the first holder holds the second circuit board in spaced relation to the first circuit board in the first direction.

主权项

1. A push switch comprising:
a keytop movable in a first direction; a switch configured to be turned on or off in response to movement of the keytop; first and second circuit boards electrically connected to the switch, an electronic component mounted on the second circuit board; a first circuit provided on the first circuit board; a second circuit provided on the second circuit board and configured to actuate the electronic component in response to a turn-on or turn-off of the switch; and a body, the body including:
a main body;a first holder provided at the main body, the first holder being configured to hold the first circuit board; anda second holder provided at the main body or the first holder, the second holder being configured to hold the second circuit board in spaced relation to the first circuit board in the first direction, wherein a main surface of the first circuit board and a main surface of the second circuit board both extend substantially horizontally in a second direction perpendicular to the first direction, and wherein the first circuit is a protection circuit.
