A motor includes a shaft presenting a shaft lead end, a switch assembly including a switch arm shiftable between a first position and a second position, and shield structure. The shaft lead end and the switch assembly are disposed axially outward of an endhsield. The shield structure is disposed axially outward of the switch arm to at least substantially restrict direct tool access to the switch arm from an axially outward position relative to the switch arm. The shield structure at least in part defines first and second tool access channels each extending radially inwardly to the shaft lead end, such that the shield structure enables direct tool access to the shaft lead end via the tool access channels but prevents or at least substantially restricts direct tool access to the switch arm via the tool access channels.
