contact sequence number is specified
by the supplying factory. Specifying the
part no is enough when placing repeat
orders.

Contact sequence
The adjacent form makes it easier to specify the contact sequence.
Switching angle
30, 45, 60, 90
o
Preferred angle: 60
o
For On-Off switches: 90
o
For main switches: 90
o
as FS 908
Changeover with interruption between 2 positions (ON-OFF-ON) not
permissible for T0, T3 and TM = 30
o
, 45
o
; for T5 (T5B) = 30
o
Star delta switch only with switching angle ≥ 60
o
Terminal marking
TM switches have consecutive terminal markings starting with 1.
Automatic (spring) return
The switching action is limited by a stop. The switch returns under spring
pressure to the last position. Where a switch has Automatic (spring) return
from both directions, a maximum of max. 3 positions can be traversed.
The Automatic (spring) return angle is ≤½ switching angle. A max of 6
contacts can be returned at the same time.
The switching angle of Automatic (spring) return TM mini rotary switch
must be ≥ 60
o
.
Fleeting contacts
The duration of the fleeting contact depends primarily on the actuation
speed. In order to actuate a contactor with a fleeting pulse, the switching
angle of the cam switch must not be less than 60
o
, since the pulse time can
be too short if the switching angle is smaller. Fleeting contact elements
always cooperate in both operating directions.
Complete rotation
Only possible with a total switching angle at 360
o
the direction of
switching can be either operating direction. The number of switch position
multiplied by the switching angle must be 360
o
, TM with 12 positions (one
every 30
o
) only available with complete rotation, not with stop.
Front plates
Front plates are part of the equipment supplied with a ‘first order of rotary
switch’ and therefore do not need to be ordered separately.
Number of contact units
Number of contact/2 = Round up to nearest whole number
The number chamber = contact unit (BE) has 1 or 2 contacts, each of which
is actuated by a cam.
In T5(B) there is a common cam for both contacts. Because of this, the
following applies for T5(B): If the total switching angle is less than 180
o
,
the contacts can be switched independently of each other. With switching
angles for greater than or equal to 180
o
, there can only be 2 contacts in the
same chamber, if their switching sequences are the same but are offset by
180
o
(e.g. TS5-4-8235 step switch)
Standard features
Same as cam switch with standard contact sequence.
Note: It is possible that the order of the contacts is altered due to technical reasons. For special switches, bridges are only
possible between an even or uneven number. Other connections must be made by the user installation.
(1) For T0-.../I1 max 4 contact units
For T3.../I2 max 5 contact units
(2) For T0 up to a max 8 contact = 4 BE
For T3: up to a max. of 12 contacts = 6 BE
