An improved command and/or set switch for digital type electronic watches which require operation of the command switch to view the display or operation of the set switch for setting the time, comprises a conducting pin extending through an opening in the side of the watch casing towards the interior module contact. A single O-ring provides a seal for the pin within the opening. A spring conductor in the form of a flat band is disposed internally of the casing and makes continuous electrical contact with the casing, this spring also biasing the pin outwardly or away from the internal module contact. With this arrangement, depression of the pin into the casing causes the inner end of the pin to electrically engage the module contact and complete a circuit from the contact through the pin and spring to the casing. The spring not only serves as the conducting medium but also as a shock absorber for the module of the casing.
