Single throw battery switch with improved contact dome

A method of assembling a switch, the switch being configured to selectively electrically couple a power source to a load, the method comprising:

• coupling a first terminal and a second terminal to a first housing, the first terminal being electrically coupled to the power source and the second terminal being electrically coupled to the load;
• positioning a biasing member and a contact within a cavity of a rotating member;
• coupling a second housing to the first housing such that the rotating member, the biasing member, and the contact are positioned between the first housing and the second housing, the rotating member, the biasing member, and the contact being rotatable relative to the first housing and the second housing;
• attaching an actuator to the rotating member, the actuator being positioned outside the first housing and the second housing, the actuator being operable to selectively move the contact between a closed position, in which the contact electrically connects the first terminal to the second terminal, and an open position, in which the contact does not electrically connect the first terminal and the second terminal,
• wherein the contact has a first contact end and a second contact end and the bias member has a first end and a second end, and wherein positioning the biasing member includes positioning the biasing member to apply a first biasing force proximate the first contact end via the first end and to apply a second biasing force proximate the second contact end via the second end;
• and
• wherein the contact and the biasing member are configured to rotate about a common axis that extends longitudinally through the contact and the biasing member.
