Toggle switches can be used to show two or three positions. Where there are three positions, one should be up, the middle one straight out, and the other one downwards. Toggle switches take up very little room.
The following recommendations apply to toggle switches:
1. A sound should be heard to indicate activation of the switch.
2. If a number of switches are used, they should be placed in a horizontal row. Vertical positioning requires more space in order to avoid accidental operation.
Table 5.3 gives detailed design recommendations for toggle switches.
