Abstract

An electronic device includes a housing, a support member coupled to the housing, a trigger member coupled to the support member, a sliding member, a first magnet member coupled to the sliding member, and a second magnet member coupled to the support member. The first magnet member includes two first magnets and a second magnet coupled to the corresponding first magnet. The magnetic pole of the first magnets is opposite to the magnetic pole of the second magnet. The second magnet member includes a third magnet and two fourth magnets. The magnetic pole of the third magnet is same as the magnetic pole of the second magnet. The magnetic pole of the fourth magnets is same as the magnetic pole of the first magnets.
