ABSTRACT:
A battery-powered transmitter which emits an audible sound or RF signal, including a housing which is mountable to the collar for a pet, for example. The present device is switchable between “on” and “off” modes of operation by means of a rotary cap whose rotational position effects switching of the device between its “on” and “off” modes of operation. Tactile and visual indication of the then-current operational mode of the device is provided by means of the rotational position of the rotary cap and indicia provided on the housing of the device and on the rotary cap itself. The rotary cap of the present invention further provides for sealing of the rotary cap with respect to the housing against foul weather conditions, including immersion in water, while simultaneously providing for rotary motion of the cap for effecting switching of the device between its “on” and “off” operational modes, employing an expansible seal between the cap and the housing.
